The present disclosure belongs to the technical field of indomethacin synthesis, and discloses a method for synthesizing an indomethacin and an analogue thereof. The method for synthesizing an indomethacin and an analogue thereof includes steps of: introducing an alkyl group, an aromatic ring or a heteroaromatic ring directly at the C2 position of indole, a carboxylic acid fragment at the C3 position of the indole, and an aroyl group at the N1 position of the indole through palladium-catalyzed reactions. The present disclosure solves a problem: most of the existing indomethacin synthesis methods are achieved by construction of an indole ring and modification; simple structural changes of an indomethacin molecule based on this synthetic strategy often require de novo synthesis; the late modification and structure-activity relationship study of the indomethacin molecule have lengthy synthetic steps.
